You need to run the primary site database server, with the primary database loaded.
Change to the tutorial directory.
Enter the following command to start a network database server running the primedb database. You should be using the TCP/IP network communication protocol on the default communications port (2638):
dbsrv10 -x tcpip primedb.db
Change to the tutorial directory.
Enter the following command to start a network database server running the repdb database, but on a different port:
dbsrv10 -x tcpip(PORT=2639) -n REPSV repdb.db
Next, you have to make entries for each of the SQL Anywhere servers in an interfaces file, so Replication Server can communicate with these database servers.
